UNITED STATES PATENT O FICE,

CHARLES 'BERNIIARDT, OF PHILADELPHIA, PENNSYLVANIA.

WEIGHING CHUTE-WAGON.

SPECIFICATION forming part of Letters Patent No. 623,976, dated May 2,1899.

Application filed November 26, 1897. Serial No. 659,812. (No model.)

To all who/7t if ntrty concern:

Be it known that I, CHARLES BERNHARDT, a citizen of the United States,residing at Philadelphia. in the county of Philadelphia and State ofPennsylvania, have invented eertain new and useful Improvements inChute- \Vagons; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to self-weighingchutewagons for the automaticdelivery of merchandise, such as coal and the like; and the presentinvention is designed as an improve ment on that class of chute-wagonsfor which an application for Letters Patent of the United States, SerialNo. 651,827, was filed by me on or about the 16th day of September,1897.

The object of the present invention is to improve and simplify theconstruction and increase the efficiency of the device withoutincreasing the cost of production.

To these ends the invention consists in the construction, combination,and arrangement of the device, as will be hereinafter more fullydescribed, and particularly pointed out in the claims.

The accompanying drawings show my invention in the best form now knownto me; but many changes in the details might be made within the skill ofa good mechanic without departing from the spirit of my invention as setforth in the claims at the end of this specification.

The same reference characters indicate the same parts of the inventionas illustrated in the several views of the drawings.

Figure l. is a longitudinal section of myimproved chute-wagon with theshafts or tongue removed. Fig. 2 is a transverse section on the line 3 3of Fig. 1. Fig. 3 is a plan view of the turn-table. Fig. 4c is a detailview of the lower end of the body-elevating mechanism, and Fig. 5 is adetail view showing a modified form of the tilting mechanism.

1 represents the running-gear, which may be of any approved form, and itis provided with the usual carrying-wheels, as shown.

2 2 denote a rectangular frame formed centrallyin the running-gearplatform, and in it is journaled a series of flanged friction-rollers 33, arranged in the same horizontal plane to support the turn-table l,which is held in. place thereon by the guide-brackets 5 5, fixed to theframe 2 2, so as to permit the turn-table to rotate horizontally withinthe guide brackets in either direction.

(3 6 represent Vertical supports arranged pan allel with each other andon opposite sides of the turn-table, and each support is provided with apair of grooved guide-rollers 3 3, arranged in the same vertical planeto receive the opposite flanges of the parallel T-shaped standards 7 7,depending from the cross-bar S. The lower ends of these T-shapedstandards are seated in the outer ends of a shoe 9, which is providedwith a central eyebolt 10, through which a chain 12 passes, the freeends of said chain being fixed to the horizontal longitudinal shaft 13,journaled in the running-gear. The rear end of this shaft is providedwith a gear-wheel 14-, which is connected by suitable gearing with thecrank-shaft 15, which is provided with the handle 10 and a ratchet-wheel17, which engages a gravity-pawl 18.

19 represents the brake-shaft, journaled in the rear end of therunnning-gear, and it is provided with the usual brake-shoes 4-7, asshown. The central portion of this brakeshaft is formed with an integraldouble crankarm 20, which straddles the elevating-shaft l3, and from theupper end of said crank-arm a brake-rod 21 extends to the brake-lever22, fulcrumed in the forward end of the runninggear and withinconvenient reach of the foot of the driver.

23 represents an arched yoke arising vertically from the cross-bar 8,and the crown of the arch is formed with a bracket 24, in which isfulcrumed a scale-beam 25, the shorter arm of which carries a link 26,from which depend two chains 27 27, the lower ends of which are fixed tothe forward end of the wagon-body 28 to support this end, and also tworods 29, which diverge rearwardly and are connected to two plates 30,which extend through guidebrackets 31 31, fixed to the outsides of thewagon-bod y near its rear end. Each plate 30 is provided with a seriesof orifices 32 and each bracket 31 with a single alined orifice 34-denotes a removable pin which is adapted to be inserted in the orificein said bracket and the corresponding orifice in the plate and extendinto an alined orifice in the side of the body to secure the plate insaid bracket and support the rear end of the body.

The chains 27 are permanently fixed to the forward end of thewagon-body, while the plates 30 are adjustably secured to the rear endof the wagon-body by means of the pins 23 )onsequently by drawing theplates out and inserting the pins in the orifices nearer their ends whenthe body is. raised the front will rise lirst,causing the body to tiltrearward, so as to discharge its contents by gravity.

It will of course be understood that the wagon-body normally rests bygravity on the usual bolsters fixed on the running-gear; but when it israised therefrom by means of the yoke the load of the body and itscontents is borne by the scale-beam and the weight of the load indicatedby the hand or pointer on the dial, as will be presently more fullydescribed lh-om the outer end of the beam-lever a rod 35 extends to arack-bar 30, which meshes with a. pinion 37, lixed on a shaft 38,journaled in a bracket 39, fixed to the yoke. 40 represents a scale-dialfixed to said bracket 39, and ll. denotes a hand or pointer fixed onsaid shaft :38, which traverses the scale-dial and indicates the poiseor equilibrium of the scale supporting the unloaded wagon.

The lower end of the rack-bar 36 is provided with a rod 1-2, which isformed at'its lower end with a weight-pan 43 to receive a series ofremovable weights it -14, part of which are for the purpose ofcounterbalancing the wagon-body and the remainder added to correspond tothe load to be weighed.

The cross-bar S is provided with a trans verse rollertiand to denotes ashoe or bracket fixed to the bottom of the wagon-body, so as to extenddownward on each side of the roller and serve as a guide for thewagonbody when tilted to discharge its contents.

In case it should become necessary to discharge the contents of thechute-wagon in a narrow street or in some cramped place where it wouldbe impracticable to back the wagon against the street-curl) the wagon isthen run alongside of and parallel with the streetcurb and the wagon-body swung around transversely to the line of the street-curb to perm itthe contents of the wagon to be discharged.

Having thus ascertained the weight of the wagon-body and having adjustedweights on the scale-pan to counterbalance the weight of the wagon-bodyand cause the hand or pointer 41 to return to zero on said scale-dial,the material to be delivered is placed in the wagon-body, and when saidwagon-body containing the material to be weighed is raised 1 from thebolsters on the running-gear by means of the yoke the hand or pointerwill indicate on the scale-dial the weight of the contents of thewagon-body.

The dealer first weighs the empty wagonbox at the yard before puttingthe coal into it by placing the necessary weights on the scale-plate,and the indicator-finger indicates on the dial what the weight of theempty wagon-box amounts to. He then places in the wagolrbox coal to theamount ordered, weighing the whole. lVhen he delivers the coal to theconsumer and prior to dumping the coal, he shows by the weights which hecarries with the chute-wagon the weight of the wagon-box and itscontents. He then dumps the coal at the place of delivery and then andthere shows to the receiver the weight of the empty wagon by means ofweights on the scale-plate, the weight at the same time being indicatedon the scale-dial. He then deducts from the weight first exhibited tothe receiver the weight last exhibited to him, and the remainderresulting shows to the cousumer or receiver at his house or other placethe exact amount of coal that has been delivered to him. Thispractically amounts to carrying the yard scales with the cluttewagon. I

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. The combination with the running-gear platform and the flangedfriction-rollers 3 journaled therein, of the turn-tabletmounted thereonand provided with the vertical supports 6 G, guide-rollers journaledtherein, the cross-brace 8 formed with the depending standards 7 '7,having a vertical movementin said supports, the arched yoke 23 fixed tosaid brace, the scale-beam fulcrumed therein, the wagon-body 28supported by said scalebeam, and means for indicating the weight of saidbody through the medium of said scalebeam, as and for the purpose setforth.

2. A chute delivery-wagon comprising a running-gear, a turn-tablejournaled in said running-gear, an arched yoke vertically adjustable insaid turn-table, a wagon-body supported by said yoke, and means carriedby said wagon-body beneath said turn-table for elevating, rotating andtilting said wagonbody, as and for the purpose set forth.

In testimony whereof I hereunto allix my signature in presence of twowitnesses.

CHARLES BERNHARDT.
